38 | * @def: set if this transport should be considered the default |

44 | * This is the basic API for a transport module which is registered by the | |
45 | * transport module with the 9P core network module and used by the client | |
46 | * to instantiate a new connection on a transport. | |
47 | * | |
aca00763 | 48 | * The transport module list is protected by v9fs_trans_lock. |
